Definitions

  • the present invention relates to the technical field of articles with a compressive effect, in particular for therapeutic use, comprising an integrally knitted piece comprising at least a first knitted tubular element and a second knitted tubular element, such as gloves with a compressive effect, without seam obtained by knitting.
  • the present invention also relates to the technical field of processes for obtaining such articles.
  • Articles with a compressive effect are used to prevent or treat venous circulation problems, particularly in the lower or upper limb, as well as pathologies linked to dysfunctions of the lymphatic system and reduce edema.
  • Venous disorders can have several origins, among these we find in particular: a stiffening of the venous wall, an alteration of the valves, an increase in the diameter of the veins, or even a congenital malformation, such as for example an angioma.
  • Articles with a compressive effect comprising an integrally knitted piece comprising at least a first knitted tubular element and a second knitted tubular element, in particular hand gloves with a compressive effect, can be used in the context of the applications cited above but also in treatment of severe burns, and in particular to prevent the appearance of hypertrophic scars and retractile bands, or to improve their appearance.
  • Articles with a compressive effect can be used in the treatment of thermal, chemical or electrical burns, the fight against functional or unsightly complications of scars (keloids, hypertrophic, flanges, etc.) and the treatment of skin graft areas.
  • the local pressure exerted on a member by an article with a compressive effect is a function in particular of the force-elongation characteristics of said article.
  • P represents the pressure, expressed in Pascals, exerted at a given point of the limb considered, 1 mmHg is worth approximately 133 pascals.
  • L is the width, expressed in meter, of the area considered of the member and n represents the number of layers of the article with compressive effect arranged on said area.
  • T is the tension, expressed in Newtons, exerted by said article when it is slipped on the lower or upper limb.
  • R is the radius of curvature, expressed in meters, at the point considered on the lower or upper limb.
  • US 2006/0021390 relates to a hand glove with a seamless compressive effect obtained by knitting at least one elastic mesh thread and at least one elastic weft thread on a rectilinear knitting machine in which the tubes corresponding to the fingers and the Palms are joined when knitting the glove.
  • Modeling and/or transfer techniques and/or varying the size of the stitches and/or the tension of the threads are used to manufacture the glove but it is not described precisely how these techniques are implemented.
  • a mesh diagram is also not described.
  • EP 2,075,361 A1 describes the manufacture of a hand glove with a compressive effect knitted on a straight knitting machine comprising two needle beds in which two tubular elements are linked by knitting by transferring stitches from the front bed to the rear bed (see fig.1 , transition from line 1 to line 2). Each tubular element is knitted in stockinette stitch every other needle or more so as to leave free needles, on the back or front bed, which will receive the stitches from the front or back bed.
  • connection by knitting between two tubular elements is thus carried out by overlapping all of the stitches of the first and second tubular elements arranged on the front and rear needle beds so that the junction obtained would be thick and uncomfortable, particularly in this example in which the connection would be made by overlapping over five meshes.
  • the tubular elements must be knitted in a planed manner, that is to say knitted one needle out of two, out of three or even more, which generates tubular elements of large gauge, for example of the order of 6 columns of mesh per centimeter or 15 columns of mesh per inch (1 inch is 2.54 cm).
  • the compressive hand glove obtained is therefore in a “large” mesh knit, to the detriment of the precision of the desired compressive effect and the comfort of the wearer.
  • plane knitting does not make it possible to manufacture small gloves precisely, that is to say limited in circumference, for example intended for children.
  • EP 1.354.525 A1 describes the process of knitting a glove by straight knitting on two needle beds to make the fingers in tubular form ( Figure 3 ), the tubular parts are made one after the other and are connected by mesh, the finger tab being made by knitting empty needles between the needles used to make the adjacent fingers.
  • the present invention overcomes the aforementioned problems in that its subject, according to a first aspect, is an article with a compressive effect, in particular a glove with a compressive effect, comprising an integrally knitted part comprising at least a first knitted tubular element and a second knitted tubular member, each having an upper end and an open lower end, the first tubular member being joined to the second tubular member at their lower ends.

  • the first tubular element comprises a first anterior portion and a first posterior portion, at level of its lower end
  • the second tubular element comprises a second anterior portion and a second posterior portion at the level of its lower end
  • the first anterior portion and the second anterior portion knitted overlap on at least one stitch, preferably at least three stitches, and said first and second anterior portions not being overlapped by the first and second posterior portions.
  • the knitting process according to the invention selected, and described below in reference to a second aspect of the invention makes it possible to knit tubular elements on all the needles of the first and second needle beds of a straight knitting machine, and not one needle out of two or more, as is necessary in the state of the technique for joining two tubular elements.
  • This arrangement contributes to obtaining a “fine” gauge for knitted tubular elements, that is to say a number of columns of stitches, and possibly rows of stitches, per centimeter greater than or equal to 8, of preferably greater than or equal to 10.
  • each of said first and second tubular elements have a number of columns of meshes, and possibly of rows of meshes, per cm less than or equal to 15, more particularly less than or equal to 13.

Finally, the rear bed 32 is straddled to the left of a needle (-1), as shown in line I11.
  • first tubular element 4 and the second tubular element 5 The junction between the first tubular element 4 and the second tubular element 5 is thus made.
  • the third tubular element 6 Once the third tubular element 6 has been knitted, it will be joined to the second tubular element 5 according to the same process and so on for the fourth tubular element 7 on the third tubular element 6.
  • a few rows of jersey stitches are knitted so that the junction of the fourth tubular element 7 in the extension of the third tubular element 6 is offset and thus follows the natural arrangement of the fingers.
  • the main tubular element 9 is knitted in the extension of the (first 4 to the fourth 7) joined tubular elements.
  • the number of needles (and therefore of stitches) on which the main tubular element 9 is knitted is equal to the number of needles (and therefore of stitches) of each of the first to the fourth tubular elements minus the number of stitches necessary for the junctions .
  • the fifth tubular element 8 is knitted separately then joined to the main tubular element 9 according to the same process junction than that described above to join together by knitting the first 4 and second 5 tubular elements at their lower ends (4b, 5b).
  • the first tubular element 4 thus comprises a first front portion 4c corresponding to at least one mesh, preferably at least three meshes arranged on the front bed 31 (see line I11), and a first posterior portion 4d corresponding to at least one stitch, preferably at least three stitches arranged on the rear bed 32 (see line I11), said first anterior portions 4c and posterior 4d being arranged at the level of the lower end 4b of the first tubular element 4 as shown in Figure 6 .
  • the second tubular element 5 comprises a second front portion 5c corresponding to at least one stitch, preferably at least three stitches, arranged on the front bed 31; and a second posterior portion 5d corresponding to at least one stitch, preferably at least three stitches arranged on the rear bed 32, said second anterior portions 5c and posterior 5d being arranged at the level of the lower end 5b of the second element tubular 5 as shown in Figure 6 .
  • first anterior portion 4c and the second anterior portion 5c knitted overlap on at least one stitch, in this specific example on three stitches, said first 4c and second 5c anterior portions n 'being not overlapped by the first 4d and second 5d posterior portions.
  • first knitted posterior portion 4d and the second knitted posterior portion 5d overlap on at least one stitch, in this specific example on three stitches, and said first 4d and second 5d posterior portions are not overlapped by the first 4c and second 5c anterior portions.
  • the junction between the tubular elements of the compressive effect article is thin and comfortable for the user.
  • the tubular elements can be knitted in “all-needle” jersey, which makes it possible to obtain a fine gauge, and thus better control of the pressure exerted and the size of the item 1.
  • the loaded stitches formed with the second elastic thread 33 are consecutive without forming looped stitches, which advantageously makes it possible to control the elasticity of the knitted piece 3.
  • the arrangement of the loads alternately on the even and odd needles between the needle beds makes it possible to improve the appearance of the knitted piece and to avoid a barring effect.
  • the compression articles according to the invention thus advantageously have a fine gauge, that is to say a number of mesh columns per cm greater than or equal to 8 and less than or equal to 15, in particular less than or equal to 13 , while allowing you to control the desired elasticity and compression.
  • the compression articles according to the invention can also be manufactured to measure and in varied sizes, even very small, in the case of compression articles for children, even young children.
